Simple but high efficiency of this circuit is a Colpitts oscillator for VHF. Ideal for higher frequencies above 50 MHz, Colpitts oscillators are used for VHF parasitic capacitance of the circuit is in parallel with the feedback capacitance desired and causes no undesired spurious resonances which may occur with the Hartley oscillator. The circuit above is a VCO FM, it is a grassroots project with grounded feedback from collector to emitter. A Colpitts oscillator is a series of designs for electronic oscillator circuits using a combination of an inductance with a capacitor to determine the frequency.

In a press release today, Nintendo announced that starting Sept. 20, the Wii U Deluxe set would sell for $299.99, down from $349.99 at launch. Also on Sept. 20, Nintendo will release a Legend of Zelda: Wind Waker bundle – complete with the game, a bunch of limited-edition artwork, and a "GamePad with Zelda-inspired gold accents" – for $299.99.  So what's behind the announcement? Well, for one thing, the Wii U has been selling rather dismally. According to Reuters, Nintendo has unloaded 3.6 million Wii U units since launch, which sounds like a big number until you consider that the Wii U launched all the way back in November of 2012. Globally, in the months spanning April 1 and June 30, the Wii U sold a measly 160,000 units. (That figure is "really, really bad" Kotaku has noted.)  But there's also the small matter of the impending launch of the Microsoft Xbox One and Sony PlayStation 4. Microsoft is said to be eyeing a Nov. 8 release date for its device; So...
